When I first heard about the Theory of Constraints in 1997 I was curious about it. I read "THE GOAL" and thought, well it seems reasonable, but hardly surprising. Then I read "CRITICAL CHAIN" and then started thinking is that all there is?
To be honest about it, from a project scheduling point of view there is not much more to it than a resource loaded critical path method (CPM) schedule with a certain amount of strategically placed contingency tasks. I was underwhelmed. To top it off, the concepts are wrapped in a second-rate novel. Um... OK. I just didn't see why anyone would care particularly much about a repackaging of existing concepts. Then I learned that Mr. Goldratt had his own institute. An institute with $10,000 Jonah programs. It got me thinking of L. Ron Hubbard.
But misgivings aside, it was clear that I was headed for a collision course with TOC. I'll cover that in some upcoming postings.
